PADDLEWHEEL FLOW SENSOR SERIES PFT

The Series PFT Paddlewheel Flow Sensor is used to monitor liquid flow rates in pipes from 1-1/2 to 40˝ (40-1016 mm). The unit has one size-adjustable sensor and is available in brass or 316 stainless steel body. The unit outputs a frequency proportional pulsed or 4-20 mA output. The pulse models are a square wave output signal with frequency proportional to the flow velocity and the 4-20 mA models have a linear output of the velocity with 4 mA equal to 0 ft/s and 20 mA equal to 25 ft/s
